COMBINED BAND-CUTTER AND FEEDER FOR THRASHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 310,417, dated January 6, 1885.

Application filed March Q8, 1884. (No model.)

To all whom it may concern.-

Be it known that I, DAVID GRUBB, of Valdron, in the county of Shelby and State of Indiana, have invented a new and Improved Band-Cutter and Feeder for Threshing-Iliachines, of which the following is a full, clear, and exact description.

My invention consists of improvements in some of the devices and arrangements of the same, comprising a feed hopper, endless carrier, rotary band-cutters, and toothed rotary spreading and feeding wheels employed for.

cutting the bands of grainsheaves and feedin g them to the th rashing-cylinders, all as hereinafter fully described, and specifically set forth in the claim.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my improved combined band-cutter and feeder. Fig. Elisa longitudinal sectional elevation of the same on the line 00 0c of Fig. 1. Figs. 3, 4, and (i are details of different forms of feeding-wheels; and Fig. 5 is a front elevation of Fig. 4.

The said combined band-cutter and feeder consists of the hopper a, in which the sheaves are placed to be delivered on an endless apron, b, to be conveyed to the thrashingcylinder. (not shown,) rotary band-cutting disks 0, and the rotary toothed wheels (7,for spreading, stirring, and delivering the grain to the thrashingcylinder, together with drivinggear for operating the carrier, cutters, and feeders, which I propose to arrange by fixing a driving-pulley, on the carrier-rollerfat the de livery end of the apron, to be driven by a belt from any available pulley on the thrashing machine, with another pulley, g, on said shaft,

from which a crossed belt, 7), runs onto'asmaller' pulley, 'i, on the shaft j ,carrying the feedwheels (Z, and shaft j also has a larger pulley, it, from which a belt, Z, runs to the pulley m on the shaft n, carryin the cutters c. I arrange these cutters c a suitable distance above the apron I), to enable said cutters to run deep enough in the sheaves to insure cutting of the bands as the sheaves are carried under them by the apron, said cutters being located directlyin front of the end 0 of the hopper and between the sides 12 of the way along which the apron runs to convey the grain to the thrasher. The feed-wheels d are similarly located between the sides 19 of the hopper at a suitable distance along the feedway from the cutters, and from the end of the way where the grain is delivcred; and directly under the shafts of the cutters and feeders I have arranged a slotted guard-plate, g, which extends beyond the cutters and feeders a suitable distance each way, and next to the hopper connects with the end 0 of the same above the opening 5, through which the grain is carried out of the hopper, so that the straw cannot rise up to and wind around the cutter-shafts as when said shafts are exposed to the grain.

I make a central longitudinal partition, t, in the hopper, for the purpose of spreading the grain by effecting better separation of the sheaves placed side by side in it by preventing them from crowding to one side or the other, as they sometimes do without such a partition. The partition also insures the placing of the sheaves in the rightdirection.

The cutters consist of circular disks with sharp edges to be pressed down in the sheaves, so as to insure the cutting of the-bands; but the feeders are required to have prongs or teeth by which to spread the grain and distribute it, and these may be made in different forms, as with the backwardly-curved front edges, as in Fig. 2, or with the rcversclycurved edges, as in Fig. 6, or with forwardly-inclined straight edges, Figs. at and 5, or the saw-tooth form of Fig. 3; and the prongs or teeth may be set laterally like saw-teeth, as represented in Fig. 5, if preferred.

In practice the endless apron I; will be pro vided with slats or bars arranged crosswise, as usual in such carriers.

The cutters 0 and feeders d are arranged in q, formed with two series of slots, as shown, a feedwdy is formed between the said guard, and extending over and secured to the sides endless belt, and sides of the hopper, substmr 10 of the hopper, a s1e1f'ies10f fiutgingzflisks, 0, 116 1 tially as set forth. a series of toothec 'eec -w ee s c mounte on i A) shafts j n above the guard-plate (j, and extend- DAV] D DRUM" I \Vitn esses:
